Submission + - Stronger winds explain puzzling growth of sea ice in Antarctica (washington.edu)

vinces99 writes: As NOAA announces a new record for the extent of sea ice in Antarctica, a new modeling study to be published in the Journal of Climate shows that stronger polar winds lead to an increase in Antarctic sea ice, even when Earth's overall climate is getting warmer. The study by Jinlun Zhang, a University of Washington oceanographer, shows that stronger westerly winds swirling around the South Pole can explain 80 percent of the increase in Antarctic sea ice volume during the past three decades. The polar vortex that swirls around the South Pole is not just stronger than it was when satellite records began in the 1970s, it also shoves the sea ice together to cause ridging. Stronger winds also drive ice faster, which leads to still more deformation and ridging. This creates thicker, longer-lasting ice, while exposing surrounding water and thin ice to the blistering cold winds that cause more ice growth. A computer simulation that includes detailed interactions between wind and sea shows that thick ice — more than 6 feet deep — increased by about 1 percent per year from 1979 to 2010, while the amount of thin ice stayed fairly constant. The end result is a thicker, slightly larger ice pack that lasts longer into the summer.

In Australia, Bosses May Get Power To Snoop On Emails 287

Numerous readers noted the proposal by the Australian government for legislation to allow employers to snoop on employees' email and IM conversations. This is being proposed in the name of protecting the infrastructure from terrorism. The attorney-general cited the Estonian cyber-attacks as a reason why such employer monitoring is necessary in Australia — never mind that the attacks were perpetrated by a lone 20-year-old and not by a foreign government or terrorist. The law permitting intelligence agencies to snoop on citizens without permission expires this June, leading to the government's urgency to extend and expand it. The chairman of Electronic Frontiers Australia said, "These new powers will facilitate fishing expeditions into employees' emails and computer use rather than being used to protect critical infrastructure. I'm talking about corporate eavesdropping and witch-hunts... If an employer wanted to [sack] someone, they could use these powers."

Submission + - U.S. Lags World In Broadband Access

An anonymous reader writes: When It Comes To Broadband, U.S. Plays Follow The Leader says a story in IWeek. The thesis is that, while broadband access in the United States rose from 60 million users in March 2005 to 84 million in March 2006, the U.S. is well behind countries like England and China. Indeed, what you may not realize is that the U.S. ranks a surprisingly poor 12th in worldwide broadband access, a situation which could threaten its ability to maintain its technological lead. Do you think this is the case; indeed, has the U.S. lost its lead already, we just haven't admitted it?

Submission + - Music execs think DRM slows the marketplace

MacGod writes: "From BBC News comes a story about a Jupiter Research survey conducted before Steve Job's anti-DRM essay, indicating that most music industry execs see DRM-free music as a way to expand the sales on digital tracks. To summarise: 54% of music execs think the current DRM is too restrictive and 62% think selling unencumbered music would be a way to boost sales. Even limiting the survey to the record labels themselves, 48% believe this. Yet, many also believe it's not going to happen without significant governmental intervention-even though most insiders think DRM is harmful, the labels are keen to stick with it.

Is this yet another sign of the typical media industry "head in the sand, refuse to change" approach, or might we be seeing the early stages or some actual change? After all, admitting you have a problem is the first step to fixing it."

John Edwards' Campaign Enters Second Life 151

politics 2.0 writes "It may not be an official effort — yet — but thanks to a grass-roots effort, John Edwards has become the first presidential candidate to set-up-shop in Second Life. Jerimee Richir, whose avatar is called Jose Rote, paid-for and developed Edwards' virtual headquarters, and, on a voluntary basis, is managing the in-world campaign. Considering that Second Life's user numbers are much smaller than other social networks, such as MySpace and Facebook — aside from generating press coverage — will campaigning in Second Life actually win many votes? Rote says yes, and that 'Second Life users are a unique audience, in that, they are first adopters. It is a smaller community, but I would argue it is a more influential community.'"
